Audio stops and requires reboot/restart to recover sound.
Comment 1 Kubilay Kocak freebsd_committer freebsd_triage 2019-09-10 05:19:17 UTC
Thank you for the report Andy

You mention it takes a reboot to recover sound. Can you describe how/when sound fails after booting, and describe the environment details within which you are testing/using audio.

Also, is this a regression from a previous version after updating to CURRENT? If so, what were the previous version(s) which sound worked without this issue

Can you please also include:

- /var/run/dmesg.boot (as an attachment)
- MYKERNEL kernel config (as an attachment)
- pkg version -v (as an attachment)

Hi HPS:

Not really sure how to answer that, depends on your definition of regression.  I can say, I have been using CURRENT as my only desktop for many years and I have seen this before.  It is possible I saw it when 12 was CURRENT but I can not say for sure.  I have definitely seen it before now on 13-CURRENT.  I failed to report it before, but yes I have seen this behavior previously in 13-CURRENT.

Mostly it happened when I was running VBOX as host with a VM guest OS running and the guest OS would be playing a web video and the sound would stop.  But this time the problem occurred while playing audio in VLC media player on the host, no VBOX running.

(In reply to Kubilay Kocak from comment #1)

I am using CURRENT with the MATE desktop environment.  I was listening to audio using VLC.  When the problem happens the normal sound stops and you hear a loud fast "buzzing" noise for about 20-30 seconds and then the noise stops.  At that point, everything on the machine is still working except for sound.  It requires a reboot for sound to work normally again.

Unfortunately, it is not possible to reliably reproduce this problem.  It can take weeks or months to show up.  I have seen this occur previously, at that time I was running VBOX as a host and the sound would stop in the guest VM.
